They indeed do become rarer. Plotting all the primes in a single row makes this apparent, like so: https://susam.net/primegrid.html#1-1-1000000 https://susam.ne

Plotting all the primes in a single row makes this apparent, like so: https://susam.net/primegrid.html#1-1-1000000 https://susam.net/primegrid.html#1-1-1000000 In fact, according to the celebrated prime number theorem, the number of primes less than or equal to n is asymptotic to n/log n, which means the density of primes near n is asymptotic to 1/log n. I have a small section about this at https://susam.net/journey-to-prime-number-theorem.html#prime-number-theorem https://susam.net/journey-to-prime-number-theorem.html#prime... if you want to read more about this.
